The NLM is told that all of the music for the Mass (a Missa Cantata) were compositions of William Byrd, the great English composer, excepting of course for the propers. The Rudgate Singers sang the Mass for Five Voices, Justorum Animae (Offertory motet), Ave Verum Corpus (Communion motet), and Ave Regina Caelorum.

The Celebrant of the Mass was Fr Stephen Maughan from English Marty's Church, Dalton Terrace, York.

Approximately 800 people were said to be in attendance.

Following the Mass there was a procession through the medieval heart of York to one of the oldest streets called the Shambles where there is the Shrine of St Margaret Clitherow. The procession then continued through the city to Ouse Bridge (over the River Ouse) which was the place of her martyrdom. From there it continued to English Martyr's Church for Benediction and Veneration of the relic of St Margaret Clitherow.
